You cannot usually download a whole eBook to read offline, due to copyright and licensing arrangements. Ebook Central titles (but not all of these) are an exception, please follow the regulations below for details.
Ebook Central platform
The Ebook Central platform has a responsive design tailored to reading on a mobile device. Ebook Central allows you to download ebooks to your mobile device or tablet to read offline using Bluefire Reader. To download the whole ebook for offline reading you will also need an Adobe ID. When you go to download an ebook the platform will take you through three simple steps to allow you to install the software you need for offline reading, allowing you to 'check out' the ebook for up to 21 days.
Some ebooks on Ebook Central may be unavailable for download due to licence restrictions imposed by the publisher. Some titles also have a limit to the amount of users who can simultaneously view the ebook. If another user has downloaded the ebook you may be unable to view it until they have returned the download.
Due to licence restrictions, a limited amount of printing or copying of ebook content is allowed on Ebook Central. Where such restrictions are in place, the amount of pages you can copy or print is clearly displayed on the ebook's title page. These restrictions reset after 24 hours allowing for further copying and printing once you have reached your limit. An increasing amount of EBC titles are available 'DRM-free' allowing unrestricted printing, copying and downloading of ebook content. For most titles you are also able to download an individual chapter or limited page range as a PDF which you can keep and will not expire.
Other services which allow downloads will also be covered by copyright law - the same as if you were photocopying part of a printed book - which usually means up to 10% or one chapter of a book and no more. Digital material is closely monitored by the suppliers, so any abuse will be noted and reported.
